Banjo is a blogging application with bells and whistles, written using the Django framework. It supports caching and skinning. It is suitable for any blog, but is most appropriate for integration into an existing Django application, such as a Satchmo store or a forum. It supports multiple blogs from one installation, each with their own skin. The blogs can be served from unique domain names, from subdirectories, or from subdomains with equal ease, without special configuration. Trackback and Pingback are supported and you can use standard blogging tools such as Ecto, Mars Edit, or ScribeFire to post to the blog.
Chyrp is a blogging engine designed to be very lightweight while retaining functionality. It has powerful theme and extension engines, so you can personalize it however you want. The code is well-documented, and it has a very strong structure that's loosely based on the MVC design pattern. Chyrp allows importation from several different blogging engines and uses a system called "feathers", which are basically templates for custom posts.
Coq au Vin is a blogging engine written in Chicken Scheme. It is designed to appeal to users who have basic Web development skills (i.e., who know HTML and CSS), are able to install their own server-side software, and would rather edit a template than press 105 buttons to customize their sites.
GitBlogger is a small tool that allows you to write blog posts in reStructuredText using an editor of your choice, commit your posts to a git repository, and then have them automatically converted to Blogger blog posts when you push your repository to another repository.

Saint CMS is a combination CMS and eCommerce package built atop a rapid development framework. It is high performance, easy to use, and provides convenient tools for creating sites with custom content types.

Sandbox is a personal Web site package that provides you with a blog, image gallery, file download area, and the ability to create miscellaneous custom Web pages. Many other blog/Web site packages like Wordpress only do one thing. Most blog packages do not also provide a good image gallery or a good downloads module. You can get these things in separate packages, but integrating them into one site is difficult, involving code bridges and incompatible skinning systems. Sandbox aims to have all of these things integrated into one package.
